Model
TRO24T4XYZ1
Description
The TRO24T4XYZ1 is a combination controller and thermostat.
The VAV Thermostat Controller is designed for simple and
accurate control of any variable air volume box in a number of
zone control configurations. Its field configurable algorithms
enable versatile implementation of required control sequences.
Applications

Cooling only with or without terminal reheat

Heating/cooling with or without auto-changeover and
terminal reheat

Pressure dependent or pressure independent

Single duct or dual duct

Serial or parallel fan power boxes (on/off or ECM)

Supply and exhaust applications

Auxiliary heating sources, such as electric baseboards, can
also be applied
Features

Backlit LCD with simple icon and text driven menus

Configurable inputs and outputs

Precise temperature control with programmable PI function

Selectable Fahrenheit or Celsius scale

Manual night setback override

Multi level lockable access menu and setpoint

Selectable internal or external temperature sensor (10 KΩ)

Changeover by contact or external temperature sensor

Pressure sensor input with air flow program

Selectable proportional control band and dead band

Anti-freeze protection

Typical Application
VAV applications incorporate a central unit that delivers a
controlled volume of air, which can be cooled or heated, to
multiple zones. Each zone incorporates a VAV control box with
a motorized damper to adjust the flow of air to the controlled
zone based on the demand. Some configurations include one or
more of the following: air flow pressure sensor, fan, duct heater,
duct temperature sensor, and auxiliary heat (e.g. baseboard).
